The government took 24 hours to react. First the telecoms authority TIB removed from its website a court order on the Twitter block and started contacting internet service providers to lift the ban.

Shortly after — as many of Turkey’s Twitter accounts came live again — the transport and communications ministry confirmed the move in a brief statement.

“In line with the decision made by the Constitutional Court … the measure blocking access to the Twitter.com internet site has been removed,” it said. “After the necessary technical arrangements, the site will be opened to use.”

The ban had been widely circumvented by many of Turkey’s almost 12 million Twitter users, who have instead sent tweets via text message or by adjusting their Internet settings.

– ‘Sultan has agreed’ –

Many Twitter users quickly commented on the move, with Nervana Mahmoud writing from Egypt, “Joy to the world, the Sultan has agreed”, using a common nickname for Erdogan.

Turkish journalist Adem Yavuz Arslan urged caution, warning that users should maintain the VPNs or virtual private networks they have used to get around the ban.

“Twitter has been unblocked,” he wrote. “But do not change your VPN settings yet. Because the government has the plug on the Internet. It can pull it whenever it wants.”

San Francisco-based Twitter had Wednesday reacted, tweeting: “We welcome this Constitutional Court ruling and hope to have Twitter access restored in Turkey soon.”

When the micro-blogging service wasn’t live in Turkey by Thursday morning, critics started pushing, fearing that the government may ignore the order.

A lawmaker from Erdogan’s ruling Justice and Development Party (AKP) suggested on TV that the ruling may not be implemented immediately, saying “We will evaluate the verdict”.

Sezgin Tanrikulu, a lawmaker for the secular main opposition Republican People’s Party, warned that defying the court order “would mean an abuse of power”.

President Abdullah Gul, a regular Twitter user, said “the bans on Twitter and YouTube now need to be lifted,” speaking with journalists during a visit to Kuwait.

– ‘Anchor of stability’ –

Erdogan had ordered the Internet curbs in the lead-up to key local elections last Sunday, in which his party chalked up sweeping wins despite the claims of sleaze and graft and a harsh police crackdown on protesters last June.

Polling has shown that the Twitter and YouTube bans — despite earning rebukes from Brussels, Washington, rights group Amnesty International and a host of the world’s literary greats — had little effect on Erdogan’s conservative Muslim loyalists.

Research centre Ipsos found that only 3.6 percent of AKP supporters said they had been influenced by the Internet blocks, and three quarters said the corruption claims had “no effect”.

Millions of Turks approve of Erdogan, despite criticism of a growing authoritarianism, because of the strong economic growth seen during his 11-year rule, analysts say.

“The Turkish economy is betting on Erdogan as an anchor of stability, and so are the people,” said Michael Meier of German think-tank the Friedrich-Ebert-Foundation.

“The corruption allegations are there, but at times of economic growth voters are pragmatic. That’s because there’s still enough left of the cake to go around.”

Meier said “Erdogan has been able to touch the Turkish soul and pride … To many he embodies the dream of rising from a poor Istanbul neighbourhood to head of government.”
